How do i solve for x in this matrix?

When matrices are equal, corresponding terms are equal.

... 5x - 8 = 2

... 5x = 10 . . . . . . . . add 8

... x = 2 . . . . . . . . . divide by 5

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

you divide them and then you get the answer i took this class this year
